RD-51 Scalable Readout System  Low cost APV25-S1 based system developed by the CERN-based RD51 coll.  Cost ~ $ 3/chan  RD-51 electronics group has agreed to deliver up to 40 k chan. By the end of  UVa research scientist Kondo Gnanvo is an SRS expert; assembled and operated first large SRS system (15 k chan.)

 # 6: GEM single versus double cluster identification: already demonstrated to be better than 2 mm with prototype tests.  # 7: GEM position resolution: already shown to be better than 100  m with prototype tests. Resolution for each module will be measured in lab with cosmics before delivery to BNL.  # 8: GEM efficiency. Previously been shown to be higher than 90% for standard GEM chambers. Efficiency for each module will be measured in lab with cosmics before delivery to BNL. Meeting the KPPs 14

 GEM modules to be used for AnDY already developed, prototyped and tested for for SBS; ready for production now.  GEM production Infra-structure and expertise in place at UVa; window of opportunity to build AnDY GEMs before major SBS production starts.  Use already developed and tested SRS electronics – “off the shelf and low cost”  Benefit from R&D already done to meet the AnDY schedule.
